Paul E. McKenney 9fdcb9afe0 rcutorture: Add self-propagating callback to forward-progress testing
If rcutorture is run on a quiet system with the rcutorture.stutter module
parameter set high, then there can legitimately be an extended period
during which no RCU forward progress takes place.  This can result
in false-positive no-forward-progress splats.  This commit therefore
makes rcu_torture_fwd_prog() create a self-propagating RCU callback
to ensure that grace periods are in progress for the duration of the
forward-progress test.

Note that the RCU flavor under test must define ->call(), ->sync(),
and ->cb_barrier() for this self-propagating callback to be created.
If one or more of those rcu_torture_ops fields are NULL, then the
rcu_torture_fwd_prog() function will silently proceed without creating
the self-propagating callback.
